RabbitMQ Basics

As demonstrated by the tutorials on the website, RabbitMQ can be used for everything from queuing background work to building RPC systems. To use RabbitMQ effectively, it is important to understand the core concepts: queues, exchanges, bindings, and messages. The documentation on rabbitmq.com is excellent, so I won't go into much depth, but it's worth briefly mentioning the core ideas.

Basic Terminology

Exchanges are where messages are sent. Every time a message is pushed in to RabbitMQ, it goes through an exchange.

How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.
Use production SSL certificates locally. This is annoying

This re-styles your sublime text sidebar to be dark, it fits default Monokai theme.

Save the Default.sublime-theme file into packages/Theme - Default, make a backup of your original if you want to be able to go back easily.

Based on:

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

Install

Either copy the aliases from the .gitconfig or run the commands in add-pr-alias.sh

Usage

Easily checkout local copies of pull requests from remotes:

git pr 4 - creates local branch pr/4 from the github upstream(if it exists) or origin remote and checks it out
git pr 4 someremote - creates local branch pr/4 from someremote remote and checks it out

Git notes

Start

Install Git
Create a GitHub account
Open Terminal /Applications/Utilities/Terminal.app

Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.

What can you say?

	import contextlib
	import subprocess

	# Unix, Windows and old Macintosh end-of-line
	newlines = ['\n', '\r\n', '\r']
	def unbuffered(proc, stream='stdout'):
	stream = getattr(proc, stream)
	with contextlib.closing(stream):
	while True:
	out = []

	Download and unzip the tar.gz:

	sudo mkdir /usr/local
	sudo mv ~/Downloads/apache-tomcat-7.0.* /usr/local
	sudo ln -s /usr/local/apache-tomcat-7.0.* /Library/Tomcat
	sudo chown -R <your OSX username> /Library/Tomcat
	sudo chmod +x /Library/Tomcat/apache-tomcat-7.0./bin/.sh
